Reimaging machines encrypted with DE 7.2.1

Configuration Manager CB 1702 environment

I have a couple test systems encrypted with McAfee Drive Encryption 7.2.1, and when I go to reimage them (wipe the drive and start over clean), the process fails and I'm getting this error in my SMSTSLOG:

This was never a problem before, so DE 7.2.1 is doing something new. I've gone through documentation and not found much useful. I did use their "EpeWinUpgradeTool64" to install McAfee drivers in to my boot.wim, but that didn't help.
